Achieving the best insulation system for your application is not easy. Besides the right choice and implementation of the insulation, the insulation protection system also plays an important role. Specific uses call for specific solutions. Certain processes require a fully watertight and closed finish. Strong and easy to clean, with great durability and chemical resistance. An insulation protection that results in a high amount of operational safety, low maintenance costs and limited energy costs. ROCKWOOL Technical Insulation offers an innovative protection system for ROCKWOOL ProRox insulation: ProRox GRP 1000.

ProRox GRP 1000: for a durable insulation protectionProRox GRP 1000 is a fiberglass reinforced polyester mat positioned between two sheets of film. The material contains resins, fiberglass and special fillers and is ready to use. Unprocessed it is soft and malleable. In this state, ProRox GRP 1000 can be cut or trimmed into any shape which makes it easy to apply to the insulation. The polyester subsequently cures under the influence of ultraviolet (UV) light. After curing, ProRox GRP 1000 is absolutely watertight and is able to give optimal mechanical protection.

The advantagesThe ProRox GRP 1000 system has important advantages that enhances the quality of your work.

Great durability: ProRox GRP 1000 forms a seamless connection that offers a watertight protection to the ROCKWOOL insulation. It minimizes the damaging effects of the weather (wind, rain, seawater, etc.) or general wear and tear. It is chemical- resistant and withstands mechanical stresses (i.e. can be walked upon).

Easy to clean: ProRox GRP 1000 can withstand pressure washing. Cleaning with water is possible without damaging the insulation.

Low start-up costs: processing and installation takes place on location. This makes investments for the prefabrication of the insulation protection unnecessary.

Flexible use: cold and hot insulation, underground and above ground cables and pipes, on and offshore. ProRox GRP 1000 moulds itself to every technical application.

ProRox GRP 1000,the watertight insulation protection Food & Pharmaceutical

The food industry and the pharmaceutical sector also adhere to very rigorous standards and rules as far as insulation is concerned. Those strict rules and regulations must prevent dirt, bacteria or moisture from accumulating in the (damaged) insulation.

ProRox GRP 1000 is the ideal solution for making insulation around pipes, cables, storage tanks, installations, etc. sealed, watertight and damage-resistant.

In addition, ProRox GRP 1000 can withstand pressure washing. The cladding material can be cleaned with water without causing any damage.

Thanks to the low permeability of ProRox GRP 1000 as well as the thermal resistance of ROCKWOOL insulation, a durable insulation of dual temperature systems is possible.

Tank roof insulationConventional systems for tank roof insulation are often sensitive to damage from the weather (water, wind, etc.) and the effect of chemicals. The costs of maintenance and the consequent lowered operational safety resulting from this are often higher than the (energy) cost-savings that are realized by the insulation. For this reason many tank roofs, especially in the lower temperature ranges, are not insulated.

ProRox GRP 1000 is applied directly on ROCKWOOL tank roof insulation on site. Since direct cladding supports are no longer needed, it fits to all parts of the tank seamlessly and has an unequalled hardness and mechanical strength (e.g. can be walked upon).

Where there are high wind stresses, a special cable construction can be applied that will keep the insulation in its place under the most extreme weather conditions.

An anti-slip coating is available that can easily be installed to ProRox GRP 1000.

The absence of cladding supports virtually eliminates any risk of corrosion under insulation.

This ensures perfect protection to the insulation and storage tank which guarantees the durability of the insulation.

ProRox GRP 1000, the watertight

insulation cladding.

Offshore & MarineBecause of the extreme weather conditions (rain, wind, temperature fluctuations,...) and the action of sea salt and chemicals, the insulation of (upper deck) ship’s pipelines and storage tanks and offshore installations sometimes have to endure a lot of punishment.

ProRox GRP 1000 prevents the problems which can compromise safety. The watertightness, high chemical resistance, mechanical strength and seamless finish guarantee that.

Moisture penetration leading to corrosion under insulation is virtually impossible.

ProRox GRP 1000 can be installed on site around equipment. Missing or complicated prefabricated parts of the cladding now are a thing of the past.

Petrochemical industryThe footprint of a petrochemical plant is considerable. For example, a medium sized oil refinery contains 222 km of insulated piping and more than 26 football pitches (130,000 m²) of insulated equipment, vessels and tanks. The temperature inside can easily go up to 600°C or more. Insulation is therefore essential to keep the heat inside.

In many cases the insulation gets damaged by mechanical impact, the ingress of water and/or potentially corrosive media. The effect of these damages is substantial. In many cases the reduction in heat loss is up to 40% less than expected, the annual maintenance costs for corrosion can be overwhelming.

In order to meet the technical requirements of today’s stringent operational environments, ProRox GRP 1000 has undergone a rigorous programme of extensive testing to provide the reassurance needed to give the user confidence in the effectiveness and protection provided by ProRox GRP 1000.

ProRox GRP 1000 has been extensively developed to be used across a broad range of applications in the petrochemical industry typically and many other installations in land based or offshore environments. Even in environments where aggressive chemicals are exposed to the insulation surface ProRox GRP 1000 gives excellent protection for:

Pipework Vessels Tanks Valves

The benefitsApplying ProRox GRP 1000 offers you the opportunity to enhance the quality of your insulation work and thus reduces the energy costs and sustainability of your plant.

No water ingress: ProRox GRP 1000 is a seamless protection, which provides a watertight insulation system which reduces the risk of corrosion under insulation.

ProRox GRP 1000 is a material that is very easily installed. Because of its great malleability, it allows itself to be shaped without difficulty, after which it acquires its unique properties by the curing process. Because of its almost endless applications, it is impossible to give a working description for each situation. The most essential information is stated in the processing instruction below. More information is available upon request.

The right toolsThe only tool required are a tape measure and knife. Use your X-acto/Stanley knife to cut on the cutting table. Clean the tools thoroughly after use. The transparent tape is perfectly suitable for evening out the seams and surfaces.

ROCKWOOL ProRox insulationFor a simpler installation and better adhesion, ROCKWOOL ProRox insulation should be coated with an aluminum foil. An overview of the appropriate insulation is mentioned below.

Always apply the insulation as tight as possible around or on top of the object. Unfaced areas should be covered with alu-foil. At temperatures below 200°C a support construction is in general not necessary. For flat surface where high wind stresses can occur the insulation should be mechanically fixed by a special support construction.

Getting started: ProRox GRP 1000 has two distinct faces. The underside is equipped with a dark foil and has a slightly rougher surface. The upper surface has a transparent film and has a smooth-er surface. When the bottom film is removed, ProRox GRP 1000 is tacky to aid application. The top film should be removed after curing. The upper surface (with film) of the material is located on the outside of the roll. Cut or trim the necessary amount of ProRox GRP 1000.

Make sure that the roll always remains hanging in the box. Close the box after use. This will prevent curing of the roll by incoming daylight or UV-light. Cut or trim the pieces of ProRox GRP 1000 needed on a flat table.

To ensure the highest level of quality and safety always apply ProRox GRP 1000 under dry conditions within a well ventilated environment.

UV-light safetySince ProRox GRP 1000 is a material that cures under the influence of ultraviolet light (UV-A), it is necessary to supply artificial lighting when there is insufficient daylight (sunlight). For the best results, keep the following information in mind.

When using artificial lighting, different forms of UV-light can be released, depending on the type of light source: UV-A-, UV-B- and UV-C-light. Looking at the lamps at a short distance is not good for the eyes, regardless of the type of UV-radiation (see actinic conjunctivitis, snow-blindness). Because of the high intensity of the light, you must especially be careful of UV-C-radiation. Is direct contact with the UV-light not avoidable? In that case, use protective clothing (UV-glass-es, etc.). Also, maintain your distance. At a distance of more than 4 meters, the danger is almost negligible. The UV-400 W HPA Power lamp is recommended as a standard. This is a UV-lamp with a very high UV-A capacity.

ROCKWOOL Technical Insulation offers UV lamps and bulbs as a service for its customers. More information is available upon request.

2. Use a flat table for the cutting and trimming of ProRox GRP 1000. Avoid direct contact with sunlight during use.

1. Open the box and make sure that the roll remains hanging in the box.

3. Cut or trim the pieces ProRox GRP 1000 needed on a flat table.

4. Close the box after use. Always store ProRox GRP 1000 horizontally in the original packaging in an ambient temperature of a maximum of 25°C.

Important! Always apply an overlap of at least 2,5 cm to secure a good adhesion. At seams where distorting stresses may occur (bends, etc.) a supplementary adhesive strip should be used. During the installation, it may be necessary to allow certain sections to cure and other sections not to cure. Parts, on which later connections with ProRox GRP 1000 must be made, should not yet be allowed to cure. Make sure that these sections are covered up with a UV-blocking tape (e.g. alu-tape).

Technical dataInstallation exampleThe installation demonstrated below shows an example of pipework with a temperature less than 90°C.

DefinitionProRox GRP 1000 is a fiberglass-reinforced 1-component polyester (GRP) that in unprocessed state is soft and malleable. The material contains resins, fiberglass and special fillers and is ready to use. ProRox GRP 1000 can be cut or trimmed into any shape which makes it easy to apply to the insulation. The material cures under the influence of ultraviolet light. Once cured, ProRox GRP 1000 has an extremely high level of hardness and mechanical strength compared to conventional polyester. In addition, ProRox GRP 1000 is impermeable and resistant to a large number of chemicals.

AncilliariesAs accessories, UV-lamps and safety goggles are available upon request. Besides these, we also offer ProRox GRP 1010, which is a UV-curing resin. This resin enhances the adhesion between already cured and newly applied uncured ProRox GRP 1000. Therefore, it is used in case of repairs or in order to continue working on already cured ProRox GRP 1000.

CuringThe curing will depend upon the ambient temperature and the intensity of the UV-light. Under the influence of sunlight or 400 W UV-lamps, placed at a distance of 0.5 meters, ProRox GRP 1000 cures in 30 minutes (T 20°C / RH 50%).

Packaging and storageProRox GRP 1000 is supplied in rolls of 10 m in length and 1 m in width, packed in boxes. Each roll (including packaging) weighs approx. 38 kg. The storage life is 6 months (after date of delivery). The contents measure 10 m² per roll. Always store ProRox GRP 1000 in the original packaging in an ambient temperature of a maximum of 25°C. Avoid direct contact with sunlight during use.

Exposure to sunlightApplying a coating/paint may be required to improve the cosmetic appearance and/or the durability of ProRox GRP 1000. This is especially relevant if ProRox GRP 1000 is exposed to direct sunlight with a high UV intensity which is common for warm, sub-tropical and tropical climates.

Step 1Cut the ProRox GRP 1000 into the pieces/sizes needed and loosen the bottom foil.

Step 3Remove the top foil to create an overlap of at least 2,5 cm.

Step 5Remove the top foil.

Step 2Remove the bottom foil while applying the strip directly on top of the alu-faced ProRox or SeaRox insulation.

Step 4Curing with UV-light.

Step 6Resistant to mechanical impact and water!
